3 Claims.

The present invention relates to a deodorizing device and more particularly to a device adapted for installation within existing toilet flushing tanks.

The primary objects of the instant invention are to provide a device of the general character above indicated which is simple yet rugged in construction; to provide such a device which is highly efiicient and utilitarian in use; to provide such a. device which may be readily and conveniently installed; and, to provide such a device which is reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:

Figure 1 is a vertical longitudinal sectional view of a conventional type toilet flushing tank and the deodorizing device detachably installed therein;

Figure 2 is a sectional view thereof on line '2--2 of Figure 1; and

Figure 3 is an enlarged fragmentary view of the device per se in vertical section.

Referring then to the drawing wherein like parts of the device shown are designated by the same numerals in the several views, a conventional type toilet flushing tank, generally designated Ill having an outlet port I I, is provided with an intake conduit ii for supplying water to the tank when the ball float 13 drops in instances after the tank is flushed.

A ball valve I4 disposed upon its seat is elevated therefrom when the tank It! is flushed by means of the actuating lever 15 through a pair of articulated links l6, 11, the upper of which is pivota-lly connected at its upper end to the actuating lever l5 and the lower of which is rigidly secured to the ball valve l4 vertically slidably embraced within a vertically apertured finger I8 of the bracket I9 secured to the intake conduit l2 in a lateral disposition relative thereto.

A smaller tank 20 whose upper end is provided with a pair of spaced hooks 2| along its rearward upper length is suspended thereby within the tank ill from the rear wall thereof below its removable cover 22 which tank 20 is adapted to hold a liquid deodorizer.

A'vertically disposed J-shaped conduit 23 depends from the tank 20 and is in communication therewith through its longer length and its upturned shorter length is provided with a vertically apertured plug 24 within which is seated a normally closed valve 25.

A pair of spaced laterally disposed arms '26 fixedly secured to the longer length of the J -shaped conduit 23 are each provided at their outer free ends 2'! with vertically aligned apertures and a 2 vertically disposed rod 28 slidably disposed within the spaced apertures and having a vertically movable frictionally adjustable ball float 29 is adapted to engage the upper end of the st m 30 of the valve 25 to open the same and thereby release liquid deodorizer from the tank 20 into the flushing tank [0.

Operation In operation, lifting of the actuating lever IS with flushing of the tank I 0 causes the vertically adjustable ball float 29 to drop by gravity, thereby opening the valve 25 to admit liquid deodorizer which mixes with the outfiowing water within the tank In. After the tank has been flushed, new water admitted thereto through the intake conduit I2 lifts the adjustable ball float 29 and its rod 28 causing the valve 25 to close thereby preventing further admission of the liquid deodorant until the next flushing of the tank Hi.

It will thus be seen that the device herein shown and described is simple yet rugged in construction, is highly efficient and utilitarian in use, it may be readily and conveniently installed, and is reasonably economical in manufacture.

While but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the device shown may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.

I claim:

1. A deodorant tank adapted for disposition within a toilet flushing tank said deodorant tank having a J -shaped conduit depending therefrom and in communication therewith at its upper longer length, a normal-1y closed valve within the lower shorter length of the conduit, said valve having a vertically projecting stem, a guiding member secured to the longer length of the conduit, projecting laterally therefrom and having a vertical aperture therein aligned with the valve stem, a rod vertically slidably disposed within the aperture whose lower end is adapted to slidably engage the valve stem, and a ball float carried by the rod and adapted to fall with the liquid level in the flushing tank whereby the lower end of the rod engages the said valve stem and unseats the valve so that the deodorant can pass from the deodorant tank into the flushing tank during the discharge of the lower most portion of water from the flushing tank.

2. A deodorant tank adapted for disposition Within a toilet flushing tank said deodorant tank having a J-shaped conduit depending therefrom and in communication therewith at its upper longer length, a normally closed valve within the lower shorter length of the conduit, said valve having a vertically projecting stem, a guiding member secured to the longer length of the conduit, projecting laterally therefrom and having a vertical aperture therein aligned with the valve stem, a rod vertically slidably disposed within the aperture whose lower end is adapted to slidably engage the valve stem, and a ball float vertically adjustably carried by the rod and adapted to fall with the liquid level in the flushing tank whereby the lower end of the rod engages the said valve stem and unseats the valve so that the deodorant can pass from the deodorant tank into the flushing tank during the discharge of th lower most portion of water from the flushing tank.

3. A deodorant tank for disposition within a toilet flush tank, said deodorant tank having a liquid conduit depending therefrom and in com munication therewith, said conduit being reversel curved at its lower end and terminating in an upwardl facing valve controlled restricted discharge orifice, a normally closed valve having avertically extending stem disposed within the discharge orifice, parallel vertically spaced guide members secured to the depending portion of the conduit and extending laterally therefrom, the outer ends of said members having guide apertures therein in vertical alignment with the upper end of the vertically extending valve stem, a valve actuating rod slidably received within the guide apertures and a ball float carried by said rod and falling and rising with the liquid level within the flush tank as the flush tank is emptied and filled to effect the engagement and disengagement of the lower end of the valve actuating rod with the upper end of the valve stem to control the position of the valve in the discharge orifice and thereby the discharge of deodorant into the flush tank.
